Hi Xairflyer and everyone else who has tried tried to help

yes the pump will run when power applied directly from battery,and also by the ecu when in prime mode
thanks for the info regarding the O ring, I think a stripdown and rebuild is probably in order to answer a few questions i have regarding the update state (if any of the components) at least the bearings feel good !!!

here are some pics of the ecu boards

many thanks Adam
